6 w3c_validator_script_selinux - Security Enhanced Linux Policy for the
7 w3c_validator_script processes
8
10 Security-Enhanced Linux secures the w3c_validator_script processes via
11 flexible mandatory access control.
12 The w3c_validator_script processes execute with the w3c_valida‐
14 tor_script_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep w3c_validator_script_t
20
24 The w3c_validator_script_t SELinux type can be entered via the w3c_val‐
25 idator_script_exec_t, shell_exec_t, w3c_validator_script_exec_t file
26 types.
27 The default entrypoint paths for the w3c_validator_script_t domain are
29 the following:
30 /usr/share/w3c-markup-validator/cgi-bin(/.*)?, /usr/lib/cgi-bin/check,
32 /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
33 /usr/bin/zsh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
34 /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash,
35 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/mksh, /usr/bin/fish,
36 /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2,
37 /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin,
38 /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell,
39 /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge, /usr/libexec/cockpit-
40 agent, /usr/libexec/git-core/git-shell, /usr/share/w3c-markup-valida‐
41 tor/cgi-bin(/.*)?, /usr/lib/cgi-bin/check

44 SELinux defines process types (domains) for each process running on the
45 system
46 You can see the context of a process using the -Z option to ps
48 Policy governs the access confined processes have to files. SELinux
50 w3c_validator_script policy is very flexible allowing users to setup
51 their w3c_validator_script processes in as secure a method as possible.
52 The following process types are defined for w3c_validator_script:
54 w3c_validator_script_t
56 Note: semanage permissive -a w3c_validator_script_t can be used to make
58 the process type w3c_validator_script_t permissive. SELinux does not
59 deny access to permissive process types, but the AVC (SELinux denials)
60 messages are still generated.
61
64 SELinux policy is customizable based on least access required.
65 w3c_validator_script policy is extremely flexible and has several bool‐
66 eans that allow you to manipulate the policy and run w3c_valida‐
67 tor_script with the tightest access possible.
68 If you want to deny any process from ptracing or debugging any other
72 processes, you must turn on the deny_ptrace boolean. Enabled by
73 default.
74 setsebool -P deny_ptrace 1
76 If you want to allow any process to mmap any file on system with
80 attribute file_type, you must turn on the domain_can_mmap_files bool‐
81 ean. Enabled by default.
82 setsebool -P domain_can_mmap_files 1
84 If you want to allow all domains write to kmsg_device, while kernel is
88 executed with systemd.log_target=kmsg parameter, you must turn on the
89 domain_can_write_kmsg boolean. Disabled by default.
90 setsebool -P domain_can_write_kmsg 1
92 If you want to allow all domains to use other domains file descriptors,
96 you must turn on the domain_fd_use boolean. Enabled by default.
97 setsebool -P domain_fd_use 1
99 If you want to allow all domains to have the kernel load modules, you
103 must turn on the domain_kernel_load_modules boolean. Disabled by
104 default.
105 setsebool -P domain_kernel_load_modules 1
107 If you want to allow all domains to execute in fips_mode, you must turn
111 on the fips_mode boolean. Enabled by default.
112 setsebool -P fips_mode 1
114 If you want to enable reading of urandom for all domains, you must turn
118 on the global_ssp boolean. Disabled by default.
119 setsebool -P global_ssp 1
121 If you want to allow httpd cgi support, you must turn on the
125 httpd_enable_cgi boolean. Disabled by default.
126 setsebool -P httpd_enable_cgi 1
128 If you want to allow system to run with NIS, you must turn on the
132 nis_enabled boolean. Disabled by default.
133 setsebool -P nis_enabled 1
135 If you want to allow confined applications to use nscd shared memory,
139 you must turn on the nscd_use_shm boolean. Disabled by default.
140 setsebool -P nscd_use_shm 1
142
146 The SELinux process type w3c_validator_script_t can manage files
147 labeled with the following file types. The paths listed are the
148 default paths for these file types. Note the processes UID still need
149 to have DAC permissions.
150 w3c_validator_rw_content_t
152 w3c_validator_tmp_t
155
159 SELinux requires files to have an extended attribute to define the file
160 type.
161 You can see the context of a file using the -Z option to ls
163 Policy governs the access confined processes have to these files.
165 SELinux w3c_validator_script policy is very flexible allowing users to
166 setup their w3c_validator_script processes in as secure a method as
167 possible.
168 The following file types are defined for w3c_validator_script:
170 w3c_validator_script_exec_t
174 - Set files with the w3c_validator_script_exec_t type, if you want to
176 transition an executable to the w3c_validator_script_t domain.
177 Paths:
180 /usr/share/w3c-markup-validator/cgi-bin(/.*)?, /usr/lib/cgi-
181 bin/check
182 Note: File context can be temporarily modified with the chcon command.
185 If you want to permanently change the file context you need to use the
186 semanage fcontext command. This will modify the SELinux labeling data‐
187 base. You will need to use restorecon to apply the labels.
188
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199 semanage boolean can also be used to manipulate the booleans
201 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
